Answer:

a2+b2=c2

Step-by-step explanation:

A right triangle is a triangle in which one of the angles is a 90∘ angle. A triangle can be determined to be a right triangle if the side lengths are known. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.

Find the cost of 12 items if the cost function is C(x) = 2x +12
pantera1 [17]

Answer:

$36

Step-by-step explanation:

we need to find the cost of 12 items, and the function of determining the cost is C(x)=2x+12, where x is the number of items (the input value of the function)

we know that there are 12 items, so in this function, x=12

substitute x as 12 in the function; the x in C(x) also gets substituted as 12, as 12 is the input value and the value of C(x) is the output

C(12)=2(12)+12

multiply

C(12)=24+12

add

C(12)=36

that means, for 12 items, the cost will be $36

11. This picture shows a table in the shape of a regular hexagon.
disa [49]

Answer:

Sum of interior angles = 720°

One interior angle = 120°

Step-by-step explanation:

Sum of interior angles = 180°(n-2)

Where n is the number of sides in a polygon

Therefore, one angle in a regular polygon will be (180°(n-2))÷n

Hence

Sum of interior angles= 180°(6-2)

= 720°

One interior angle = 720°÷6

= 120°
